In the first known case of what may be transmission of the Ebola virus from a pig to a human, a pig handler in the Philippines has tested positive for a strain of the virus, world health officials and the Philippine government announced Friday.
The development is worrying because pigs are mixing vessels in which other viruses from humans and animals exchange genetic material, possibly creating strains that are more lethal or more infectious.

Ebola? This has already jumped to humans many, many years ago, via Chimpanzees! I assume the Bible covers that too? This is hardly shocking news.
The anatomy of a pig and a human are very similar. Both are placental mammal, which means the fetus receives nourishment from the mother through the umbilical cord. Both species are also omnivores. These two things lead to the digestive track and layers under the skin to be similar. Both have complex systems that allow nutrients and dissolved gases to enter and leave individual cells throughout the body. Basically the internal cavity of the pig is very similar to that of a human, it is only smaller. The heart is located at the same place, between the lungs, the liver and a gall bladder look almost like the humans, and the whole digestive system is extremely similar to humans' digestive system.
Thought pigs and humans are similar there are still some differences. One of the major differences is the facial expression; the pigs have bigger ear, they also have a tail. Also pigs have different feet, position and number of toes on their feet .
Ebola hemorrhagic fever is potentially lethal and encompasses a range of symptoms including fever, vomiting, diarrhea, generalized pain or malaise, and sometimes internal and external bleeding. Mortality rates are extremely high, with the human case-fatality rate ranging from 50–89%, depending on viral subtype.[5] The cause of death is usually due to hypovolemic shock or organ failure.
Ebola is potentially lethal, and, since no approved vaccine or treatment is available, it is classified as a biosafety level 4 agent, as well as a Category A bioterrorism agent by the Centers for Disease Control and Prevention. It has the potential to be weaponized for use in biological warfare.[6] Its effectiveness as a biological-warfare agent is compromised by its extreme deadliness and its level of contagion: A typical outbreak spreads through a small village or hospital, infects the entire population, and then runs out of potential hosts, dying out before reaching the wider community. It is also significant to note that none of the strains of Ebola known to cause disease in humans has been found to be airborne—only the strain known as Ebola Reston (after the city of Reston, Virginia where it was first identified in Green Monkeys) is believed to be airborne.

I am glad that I do not eat pork. But as said Ebola going from human to human is not new.

No the issue is the potential for ebola to be directly into a world food source. Ebola, normally transmitted in person to person contact or in rare cases "airborn", kills so fast it can't spread outside a few poor souls. But, a dormant form in the food supply could be triggered from seemingly nowhere.
Ebola Reston in pigs and humans in the Philippines - update 31 March 2009 -- On 16 February 2009, the Government of Philippines announced that a slaughterhouse worker who has daily contact with pigs tested positive for antibodies against the Ebola Reston virus. This brings to six, out of a total of 141 people, who have tested positive for Ebola Reston antibodies in the Philippines since testing began in December 2008. All six people who were antibody positive reported occupational exposure to pigs. The Philippine Department of Health has said that all six people who tested positive appear to be in good health. Pig-to-human transmission is believed to be the most likely source of infection. To date, since the first human to develop antibodies against Ebola Reston was reported in 1989, no significant human illness has been reported in association with Ebola Reston infection. However only a very small number of humans with Ebola Reston antibodies have ever been detected, and all were healthy adult males. The threat to human health is likely to be low for healthy adults but is unknown for all other population groups, such as immuno-compromised persons, persons with underlying medical conditions, pregnant women and children. More studies are needed to better understand the public health implications of Ebola Reston in humans and efforts should be made to reduce the risk of human infection. Ebola Reston virus species belongs to the Ebola genus in the Filovirus family, a genus that comprises other Ebola species that are known to be highly pathogenic for humans. All members of the Filovirus family are only handled in laboratories with the highest level of biosecurity. Recent cases in the Philippines mark the first time that Ebola Reston has been found in pigs, and the first time that suspected transmission from pigs to humans has occurred.
